What Is a Transient Ischemic Attack (TIA)?
A TIA occurs when there is a low flow of blood or a clot briefly blocks an artery that supplies blood to the brain. With a TIA, you may have the same above symptoms as you would have for a stroke. But the symptoms only last a few minutes or few hours and then resolve.
A TIA is a medical emergency because it is impossible to predict whether it will progress into a major stroke. If you or someone you know experiences any of the above symptoms, get emergency help. Immediate treatment can save your life and increase your chance of a full recovery.
Findings show that someone who has experienced a TIA is 10 times more likely to suffer a major stroke than a person who has not had a TIA.
How Is Carotid Artery Disease Diagnosed?
There are often no symptoms of carotid artery disease until you have a TIA or stroke. That's why it's important to see your doctor regularly for physical examinations. Your doctor may listen to the arteries in your neck with a stethoscope. If an abnormal sound, called a bruit, is heard over an artery or vascular channel, it may reflect turbulent blood flow. That could indicate carotid artery disease.
Listening for a bruit in the neck is a simple, safe, and inexpensive way to screen for stenosis (narrowing) of the carotid artery. As a screening test, though, it's inexact. Some experts believe that bruits may be better predictors of atherosclerotic disease rather than risk of stroke. Be sure to let your doctor know if you have had any symptoms, such as those listed above.
Your doctor may also use a test to diagnose carotid artery disease. Possible tests include the following:
